Abstract: The housing comprises an actuating lever (8) articulated about a transversal spindle (13), and a mechanism (16), controlled by the lever, capable of driving, in opposite direction, two rods (17, 18); each rod is provided, at its end farthest away from the housing, with a bolt, in order to bring about a locking at an upper point and a lower point, respectively. The actuating lever (8) comprises a unilateral thrust organ (19) capable of co-operating with one or two complementary abutments (21, 22) provided for on a driving organ (23) of the mechanism (16), whereby the lever (8) may be tilted from one position into another, to co-operate with the appropriate complementary abutment (21, 22), in order to selectively allow the fitting onto a "right-hand" or "left-hand" door.

Abstract: The antipanic lock comprises at least a bolt and an actuating rod pivotingly connected to a door by a unit formed by at least two housings fixed onto the door and two levers (2) integral, towards their one end, with the actuating rod and pivotingly mounted, at their other end, into an associated housing (4); said lock comprises a torsion spring (10), in a first dihedron corresponding to a first direction of opening of the door, the actuating rod and the levers (2) towards a neutral position, one of the levers being a control lever co-operating with members in order to actuate the bolt.

Abstract: Safety-drum antipanic lock comprising a bolt (3, 103), an actuating rod pivotingly connected to the door, at each of its ends, by means of a unit formed by a housing (1, 101) fixed onto said door and a lever (2, 102) pivotingly mounted, in said housing (1, 101), at least one lever (2, 102) being an actuating lever cooperating with components of its housing (1, 101) to actuate the bolt (3, 103). The housing (1, 101) of the actuating lever (2, 102) is associated with at least a safety-drum (19, 20; 120) driving a bit (21, 23; 151) co-operating with actuating means for said housing to actuate the bolt (3, 103). Said housing (1, 101) of the actuating lever (2, 102) comprises at least two different operating means (14, 15a, 15b; 114) capable of separately co-operating each with a drum (19, 20; 120) to actuate said bolt (3, 103).
